Product analysis

61 out of 100

GABA 750 mg may offer short-term calming support, though small trials in specific settings leave lasting everyday stress relief uncertain.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality20

The GABA preparation is not clearly identified. That makes it difficult to compare the serving with the specific preparations behind the limited evidence.

Ingredient Transparency63

The GABA amount is disclosed, making serving comparisons straightforward. Its preparation is unspecified, limiting a closer comparison between supplements.

Value For Money100

The serving offers favorable value for its GABA content. That price advantage does not resolve uncertainty about which preparation is supplied.

Customer Satisfaction84

Customer satisfaction is positive across thousands of ratings. Those buyer impressions do not establish a reliable calming or sleep effect.

Product Focus64

The single active gives the formula a clear calming purpose. Evidence is most relevant to short-term responses during stressful tasks, with less certainty for lasting mood or sleep improvement.
